drm/i915: Fix watermark calculations for gen12+ CCS+CC modifier

Take the gen12+ CCS+CC modifier into account when calculating the
watermarks. Othwerwise we'll calculate the watermarks thinking this
Y-tiled modifier is linear.

The rc_surface part is actually a nop since that is not used
for any glk+ platform.
